Canadian developer Keynote Theme Park has released two new themes for Apple’s Keynote presentation software. Da Vinci (US$19.95) features 61 transparent versions of the master artist’s notebook illustrations that you can use for slide backgrounds in addition to three fonts, including one based on his own handwriting. It was created in 1024 x 768 resolution and includes a Photoshop Action that turns any image into a sepia-toned illustration, making it blend with Da Vinci’s work. In addition, the company has released Titanium Jr., a free 800 x 600 resolution theme that comes with five photo cutouts. Finally, Keynote Theme Park has also posted on its Web site a video tutorial that shows how to create photo cutouts for any slide background.
